Kill Switch
The kill switch blocks all network traffic that does not go through the VPN tunnel. This prevents data leaks during connection drops.
Enabling
- On the Status page, toggle the Kill Switch on
- Or select Kill Switch from the tray menu
Allowed traffic
| Traffic | Reason |
|---|---|
| Loopback (127.0.0.0/8) | Local services (localhost) |
| LAN (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16) | Local network, printers, NAS |
| WireGuard endpoint (UDP) | Connection to VPN server |
| VPN subnet | Traffic through tunnel |
| DHCP (UDP 67/68) | IP address assignment |
| Everything else | Blocked (inbound and outbound) |
Disabling
Toggle the kill switch off — all firewall rules are removed immediately.
Important: If the app crashes with the kill switch active, the firewall rules persist and internet is blocked. They are automatically cleaned up on the next app launch.
